A hard disk drive is a large capacity data storage unit that can be installed inside
Your Amiga 2000. A hard disk can store more data than a floppy disk, and files
stored on hard disk can be accessed more quickly.
To use a hard disk, you must install the A2091 SCSI Controller in your A2000. The
Controller acts as a link between the hard disk and the Amiga 2000's system.
In addition, the A2091 can function as a SCSI "host adapter,” allowing you to connect
one or more SCSI storage subsystems, such as hard disks, tape streamers, or
combined disktape systems, Hard disks and SCSI subsystems are available from
your Commodore-Amiga dealer.

Introducing the A2091-40/A2091 =x. [c
Chapter 1:Introducing the
A2091-40/A2091
The A2091 Hard Disk Controller is an internal SCSI controller card and expansion
memory unit for the Amiga 2000. The A2091-40 consists of an A2091 and a Quantum
40-megabyte SCS! hard disk. Installing a A2091-40 in your Amiga 2000 converts
it Into an Amiga 2000HD. If you have an Amiga 2000HD or an Amiga 2500, you
already have an A2091-40 installed.
The A2091 connects to an expansion slot inside the Amiga and comes with a floppy
disk containing all the software required for operation.
The A2091 includes the following features:
Sockets for 512KB, 1MB, or 2MB of fast random access memory (RAM) chips
Direct Memory Access (DMA) for fastest possible operation
Internal and external connectors for the use of Small Computer Standard
Interface (SCSI) expansion devices
© Autoboot ROMS to allow you to boot your system from the hard drive, if you
are using Kickstart 1.3
The A2091-40 package includes a Quantum ProDrive 40S (40-megabyte SCSI hard
disk), a 50-pin ribbon cable, and all the parts required to mount the hard disk and
controller card.
With the addition of the A2091-40/A2091, your system will still operate normally
using the floppy disk drive.
NOTE: To obtain the full potential of the A2091, you will want to have the Kickstart
1.3 ROM installed in your Amiga 2000. With the Kickstart 1.3 ROM you will be able
to automatically boot your system from the hard disk, rather than from a floppy disk.
You can determine whether your Amiga has Kickstart 1.2 or 1.3 by starting your
‘system without a disk in the floppy drive. The screen will show a hand holding a
Workbench disk, with the version number below it. If the version number Is 1.2,
your Amiga is using Kickstart 1.2. Please see your Amiga dealer conceming the
ROM upgrade. If the version number is 1.3, your Amiga already has Kickstart 1.3.

Chapter 3: Installing the A2091-40/A2091
WARNING: Commodore will not be responsible for any injury or damage
resulting from improper installation. Such improper installation will also void
the warranties on the A2091-40/A2091 and the Amiga 2000. Read this manual
before attempting to Install the A2091. Turn the computer off and unplug the
power cord before proceeding. Installing the A2091 with the power on could
cause personal injury to yourself and damage to the equipment. Make sure
that nothing is attached to the computer. Disconnect all peripherals and power
cords, and put them aside.
Most hard disk failures occur because of improper handling: never subject a
hard disk to electrical or physical shock.
Although you can install multiple A2091 controller cards in your Amiga, you
may only have one card-mounted 3.5" hard disk. A second card-mounted hard
disk, connected to the card's power connector, will damage the Amiga and
void the warranties on the Amiga and the A2091-40/A2091.
Unpack the A2091 and make sure you have all the required parts.

3. install the hard disk
You can install a 3.5" hard disk on the A2091 card, a 3.5" hard disk in a 3.5" drive
bay, or a 5.25" hard disk in the 5.25" bay,
If you are installing the hard disk in either of the drive bays, remove all internal
expansion cards so that you can have full access to the hard disk mounting screws.
The hard disk supplied with the A2091-40 should be mounted in the 3.5" drive bay
to the left of the floppy disk drive. These instructions begin on page 3-6. If you have
an internal floppy disk drive in this bay, you can mount the hard disk on the A2091
controller card. These instructions begin below, The instructions for installing a 5.25"
hard disk begin on page 3-9.
WARNING: Although you can install multiple A2091 controller cards in your
